Clients in a data network can subscribe to CTI Services and in this regard must be reachable by the CSTA gateway (CCGW). If this is not the case, because for example an error occurs in the data network, then the transmission of unnecessary messages can be prevented or stopped. The clients can be connected via a server to the CCGW, where the server monitors the status of the clients and acknowledges the messages addressed to an unreachable client with error messages. The server is preferably an XMPP server and the clients are preferably XMPP clients. In order to permit transport of the CSTA messages via XMPP, info/query stanzas according to RFC 3920 can be used, since they have the advantage over message stanzas that they can be acknowledged by a remote station. |
